I was surfing when this software indicated there were threats on my PC. My AV (Avira) popped up and I directed to delete (i beleive). In any case it continued to come up and my AV no longer alerted me which I then noticed it had actually shut down. I tried ending some processes that looked odd in hopes the icon on my system tray would go away indicating I had stopped it. Without success I decided to reboot and see what happened. Unfortunately I got BSOD with the following:

Aproblem has been detected and windows has been shut down...

If this is first time reboot, If appears again do following: check for virus, remove hdd, etc... Run chkdsk /f then restart...

Tech info
Stop: 0x0000007b (0xF78a6640, 0xC0000034, 0x00000000, 0x00000000).

I tried booting up with Hiren's Boot CD ((Mini Windows Xp) and from that it seems the HDD is operating and not dead. I can get into files and save those I think are important. I have run KAV from this (without new definitions) and it came up empty, could not run MBAM as an error (runtime error 5003) would pop up and it would not proceed. I really don't know what I am doing with this CD and am actually afraid of messing with MBR or other utilities for fear of making matters worse. I can not boot up in safe mode, last known config or anything else for that matter.

I am running Win xp sp3 ... I am desparately in need to getting my system up somehow but dont know what to do in view of not being able to get windows going... I have spent the last 4 hours reading but am not confident enough to do anything without some guidance. HELP HELP HELP HELP

Runing Wix Xp Sp3 ..

Just ran SuperAntispyware within Hiren's CD Boot and found some issues but while the program says they are being removed after reboot and rescan they are still there:

Looks like you have found a rootkit.. to prp[erly remove this and any more can you do this.

Please go here....

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic398439.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.
